HARRY B. JONES, OF CHCAL, ILLE 1 PERMANENT PRODUCTS CMA') 'I-TGIS Original No. 1,390,994, lated Septeiiiher 2i), 3.9%,

To all whom t may concern.'

, Be it known that i, HAB-ni' B. Jenni-ig e citizen of the United States, residing in *Chicago, in the county of @ook and State of illinois', have invented a certain new7 and useful mprovernen't in Ventilated Steves,

of which the following is a specification.

My invention relates 'to that class of staves which ere employed in the construc- .10 tion of gran-:tries 4or other buildings, which are erected in sections.

There is e very considerable dein-and for buildings oi' concrete construction suitable for the storage of material other than ensilage, which contents require ventiistitni5 es for example, oorn on the colin My invention has for its objects to 7orovide a ventilated stave suitable for use in constructing storage buildings of thee'oove character, which wili permit a free clronietion of air through the Waiis of the building, but which is so constructed as to exclude rain, snow, and the like, and for its further object to provide a stave which may be so constructed as to excinde r iin7 such as rats, Without interfering with sr` oiently free ventilation.

My 'means of accomplishing the 'foregoing objects muy he more readily understood by having reference to the accompanying drawing, which is hereto annexed, endis s part of this specification, and in Which- Fig. 1 is a side elevation oi a stave con structed in accordance with my .improveleent;

Fig. 2 is a vertical sectionai View;

F ig. 3 is en end View; and

Fig. 4 isu fragmentary section of the well constructed with my improvedv .st-ave.`

Similar reference numerals refer to similar parts throughout the entire description. 'As shown in the drawing, the stave l is .provided at one side with a, convex rib 2, and at the other side with a concavity 3, which is fitted to and coincides with the oonvex rib of the next adjacent or mating steve. The convex rib extends along one ci' ,the verticel edges of the stave, and over the upper end 4 thereof, and the concevi along 50 the other vertical edge :and e 'lower end 5, as clearly shown in 1 The end JC-is formed with no* nel Dortion 6 and an inclined portion 7, and e, riorizontal portion 8 at the bottom of the in- Gerini fic-.r constrnotion loing zt hor?- i erltcnding L i 1. Y diese manned "rein e postion There being -no Het surface upon which end connecting them i .in is loro stave. ln the eenter the ste-ve form im# en inn with rainy of rios i4, defining the upper and lower 'wells of openings 12 .intermediate the ribs, which openings provide yr'for the circulation of sin The upper well 'l of the rib is sien that 'wete-r cannot pees into the silo unless it cornes in e o1' tee Yes, the Ventilating pes- ;ney narrowed that rats nel cannot through ythe stems7 elthe outer openings would he large to admit them.

It will he obvious to persons skilled in nrt, :from the foregoing description, i in eonncotlon with the drawings, 'that e f c( @structed in this mnnnernrevides l effigie ventiler 'l rovides shedding or rre-ter ie ii ironi rein or snow, and excludes the ent Small anineis. v

`Jing deserlhedymy invention, what I rein new desire to secure by Letters Patent is: i i

l. er ventilated steve consisting of a unitary I stan'tieily transverse slots constricted in 'their cross-sectional area inwrdly from one lfase oi the stave. u i v 2. A ventiiated stave comprising a plu reiity of spaced ribs formed integrally therewith, the upper face of each rib comprising s. portion in elevated position lwith Irespect to the outer edge `portion thereof, so as to divert Water sterre.l

A ventilated .stavefoogprising a slsb Dro-vided with a plurality of subtoward- Ithe :outer -faoe of the having a plurality of ribs, there being'openings through the stave intermediate said ribs, the upper wall of each rib being' slanted downwardly `and outwardly so as to shed rain and the like.

4. A ventilated stave comprising a pluf rality of spaced ribs formed integrally therewith and providing between them a series of Ventilating openings, the upper face of each rib comprising a portion in elevatedV position with respect to, the outer edge porl" 1 tion thereof, and the lower face ot each rib eomprisinfr'a ortion in de Jressed Josition i A b with respect to the inner edge portion thereof., the elevated portion of the upper face of one rib and the depressed portion `of the lower fece of the next higher rib being in 'spaced relation between the inner and ou'ter laces ofthe stave with the elevated portion of the upper face closer to the inner face of 20 the stave.

5. A ventilated stave of molded concrete comprising a plurality of spaced ribs formed integrally therewith and providing between them a Series of Ventilating openings con- 25 stricted Vin cross-sectional areainwardly from one face ot the stave, the upper face ot' each ribY comprising a portion in elevated position with respect to the outer edge portion thereof so 'as to divert water toward 30 the outer Vface Vol the stave.

n witness whereot I have Signed the foregoing speciication. f
